Take the following example which is very similar to how toJSDOM is implemented in this library:
consthtmlString="<tr><td>Cell 1 <a>Link in Cell 1</a></td><td>Cell 2</td>";constdom=newDOMParser().parseFromString(htmlString,"text/html");console.log(dom.body.firstElementChild.outerHTML);
This will return just "<a>Link in Cell 1</a>".
The reason being, <tr> and <td> aren't valid tags in HTML if it isn't inside of a <table>. So when parsing, it seems to throw those away since they aren't correct. (As the very forgiving HTML parser likes to do.) As a result, the dom.body looks like: <body>Cell 1 <a>Link in Cell 1</a>Cell 2</body> as it has stripped all of those tags. Now since the next line is expecting just one root node, when it picks the first element, it ends up picking the a since that is the only element which remains.
In my testing, it seems like using the XML parser doesn't have this issue, but I'm not sure what other issues/differences the XML parser might introduce.
